2) Beware that while our utility will let you manage links in any of our devices, and any device that uses the so-called linear databases, the utility can not be used with the linked-record type database used in many of the Insteon devices such as LampLincs, ControLincs, KeypadLincs, etc.

Thanks for the heads-up. You did not mention RemoteLincs in your list – are they also excluded for your utility?

Additionally: Is the 3 bytes in the data field for flags, cmd1 and cmd2?
